Thanks mate. For 3D stereo to work, you need two images that have been taken from slightly positions, or where the subject has rotated between exposures, so that there is a perspective difference. With the Moon, you have to use the libration effect, but the trick is to get matching phase with the right libration. As the total libration is a mix of E-W and N-S, the variation between any two lunar exposures can be in any direction at all.

For example, with two 1st quarter exposures, you might have to rotate the images so that you get an unusual position angle. The same is true of the Full Moon, of course, but at least it's a round image, and ends up less irritating (IMHO).
